Description

Technical Field

[0001] This utility model relates to the field of ultrasonic flaw detectors, and in particular to a high-precision ultrasonic flaw detector for metals. Background Technology

[0002] Ultrasonic flaw detectors are non-destructive testing tools used to detect internal defects in metallic materials. They work by emitting high-frequency sound waves that are incident on the metal material and identifying and assessing internal defects such as cracks, voids, inclusions, and inhomogeneities based on the propagation characteristics of the sound waves. However, existing ultrasonic flaw detectors still have the following problems in practical use:

[0003] Patent No. CN202022301891.8 discloses a high-precision ultrasonic flaw detector for metal. During use, the device employs a cylinder and air pump to raise and lower a lifting plate. A sliding groove and sliding rod facilitate the movement of the threaded block, moving the stage, and the flaw detector head. A speed reducer and stepper motor are easily fixed in place. A door and lock facilitate maintenance of the internal components. A first sliding groove and a first slider stabilize the lifting plate during movement. Bearings control the rotation of the threaded rod. A second sliding groove and a second slider stabilize the threaded block during movement. However, this device cannot store unused detector heads, making it prone to contamination during intermittent testing, thus reducing its practicality. Furthermore, the device requires manual replenishment of coupling agent, making operation cumbersome and impractical. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In practical implementation: such as Figure 1-6As shown, a high-precision ultrasonic flaw detector for metal includes: an ultrasonic flaw detector body 1, a connecting cable 2, and a probe head 3. The connecting cable 2 is located at the upper end of the ultrasonic flaw detector body 1, and the probe head 3 is connected to the end of the connecting cable 2. A storage mechanism 4 and a wire-binding mechanism 5 are located at the upper end of the ultrasonic flaw detector body 1, with the wire-binding mechanism 5 located on the side of the connecting cable 2. A discharge mechanism 6 is located on the side of the ultrasonic flaw detector body 1. When the device is in use, the connecting cable 2 is first connected to the ultrasonic flaw detector body 1, and then the probe head 3 is connected to the connecting cable 2. At this time, monitoring can be performed. When monitoring is not required during use, the probe head 3 is inserted into the storage mechanism 4 for storage, thereby preventing the probe head 3 from falling to the ground and getting contaminated with impurities. During storage, the connecting cable 2 is bound by the wire-binding mechanism 5. When the probe head 3 needs to be taken out for use again, the coupling agent can be replenished to the probe head 3 through the discharge mechanism 6, making it easy for the probe head 3 to be used directly.

[0024] The storage mechanism 4 includes a storage compartment 41, a slot 42, a drive motor 43, a first slide bar 44, a clamping plate 45, and a threaded rod 410. The upper end of the ultrasonic flaw detector body 1 is provided with a storage compartment 41. A slot 42 is opened inside the storage compartment 41. The drive motor 43 is embedded in the slot 42. The output shaft of the drive motor 43 is connected to the threaded rod 410. The first slide bar 44 is provided inside the slot 42. The clamping plate 45 is connected to the side of the threaded rod 410 by reverse threads. The clamping plate 45 is slidably connected to the first slide bar 44. When the device is in use, when the probe 3 is not needed, the probe 3 is placed inside the storage compartment 41. Then the drive motor 43 is started, and the drive motor 43 drives the threaded rod 410 to rotate. During the rotation of the threaded rod 410, the two clamping plates 45 connected by reverse threads slide on the side of the first slide bar 44.

[0025] A housing 46 is embedded at an equal angle on the side of the clamping plate 45. The housing 46 is slidably connected to a first connecting block 47. A spring post 48 is provided inside the housing 46, and a switch 49 is provided inside the housing 46. When the device is in use, the clamping plate 45 drives the clamping plate connected to the end of the first connecting block 47 to clamp the probe head 3 during the sliding process. During the clamping process, the clamping plate pushes the first connecting block 47 to slide inside the housing 46. At the same time, when the first connecting block 47 contacts the switch 49, the switch 49 triggers the drive motor 43 to stop, indicating that the clamping is complete.

[0026] The wire harness mechanism 5 includes a support frame 51, a knob 52, a threaded post 53, a second slide bar 54, and a limiting plate 57. The upper end of the ultrasonic flaw detector body 1 is provided with a support frame 51. The upper end of the support frame 51 is rotatably connected to a knob 52. The knob 52 is connected to a threaded post 53. The threaded post 53 is rotatably connected to the inner side of the support frame 51. The inner side of the support frame 51 is connected to the second slide bar 54. The side of the threaded post 53 is threadedly connected to the limiting plate 57. The limiting plate 57 is slidably connected to the second slide bar 54.

[0027] The support frame 51 has a threaded hole on its side, and a bolt 55 is threaded inside the threaded hole. A rubber block 56 is provided on the side of the bolt 55. The bolt 55 is located on the knob 52. When the device is in use, the probe 3 is placed inside the storage compartment 41, and the connecting wire 2 is placed at the lower end of the support frame 51. At the same time, the knob 52 is rotated, which drives the threaded column 53 to rotate. During the rotation of the threaded column 53, the limiting plate 57 slides on the side of the second slide rod 54. At the same time, the limiting plate 57 clamps the connecting wire 2 during the movement. After clamping, the bolt 55 is rotated, and the rubber block 56 on the side of the bolt 55 abuts against the knob 52, thereby increasing the friction and preventing the knob 52 from loosening.

[0028] A transparent storage box 61 is provided on the side of the ultrasonic flaw detector body 1. A second connecting block 62 is symmetrically arranged on the side of the transparent storage box 61. The second connecting block 62 is connected to the ultrasonic flaw detector body 1. A feed inlet 63 is provided at the upper end of the transparent storage box 61. A sealing cap 64 is provided at the upper end of the feed inlet 63. When the device is in use, when the coupling agent inside the transparent storage box 61 is about to run out, the sealing cap 64 can be opened and the coupling agent can be injected into the transparent storage box 61 through the feed inlet 63 to replenish it.

[0029] The discharge mechanism 6 includes an electric telescopic column 65, a connecting plate 66, and a guide pipe 67. The electric telescopic column 65 is embedded in the lower end of the transparent storage box 61. The output end of the electric telescopic column 65 is connected to the connecting plate 66. The connecting plate 66 is slidably disposed inside the transparent storage box 61. The guide pipe 67 is disposed on the side of the transparent storage box 61. The guide pipe 67 is embedded in the inner side of the ultrasonic flaw detector body 1. The guide pipe 67 communicates with the bottom end of the storage bin 41. When the device is in use, when it is necessary to replenish the coupling agent for the probe head 3, the electric telescopic column 65 is activated to push the connecting plate 66. The coupling agent inside the transparent storage box 61 is squeezed through the connecting plate 66 and reaches the bottom end of the storage bin 41 through the guide pipe 67, thereby replenishing the coupling agent for the probe head 3 inside the storage bin 41.

[0030] When using this utility model, first connect the connecting line 2 to the ultrasonic flaw detector body 1, and then connect the probe head 3 to the connecting line 2. At this time, monitoring can be performed.

[0031] When the probe 3 is not needed, place the probe 3 inside the storage compartment 41, then start the drive motor 43. The drive motor 43 drives the threaded rod 410 to rotate. During the rotation of the threaded rod 410, the two opposing threaded clamping plates 45 slide on the side of the first slide rod 44. During the sliding of the clamping plates 45, the clamping plate connected to the end of the first connecting block 47 clamps the probe 3. During the clamping process, the clamping plate pushes the first connecting block 47 to slide inside the housing 46. At the same time, when the first connecting block 47 contacts the switch 49, the switch 49 triggers the drive motor 43 to stop, indicating that the clamping is complete.

[0032] While placing the probe 3 inside the storage compartment 41, place the connecting wire 2 at the lower end of the support frame 51. At the same time, rotate the knob 52, which drives the threaded column 53 to rotate. During the rotation of the threaded column 53, the limiting plate 57 slides on the side of the second slide rod 54. During the movement, the limiting plate 57 clamps the connecting wire 2. After clamping, rotate the bolt 55. The rubber block 56 on the side of the bolt 55 abuts against the knob 52 to increase the friction and prevent the knob 52 from loosening.

[0033] When it is necessary to replenish the coupling agent for the probe head 3, the electric telescopic column 65 is activated to push the connecting plate 66. The coupling agent inside the transparent storage box 61 is squeezed through the connecting plate 66 and reaches the bottom of the storage compartment 41 through the guide pipe 67, thereby replenishing the coupling agent for the probe head 3 inside the storage compartment 41.

[0034] When the coupling agent inside the transparent storage box 61 is about to run out, the sealing cap 64 can be opened and the coupling agent can be injected into the transparent storage box 61 through the feed port 63 to replenish it.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
